Abstract
The authors propose an efficient method of implementing the Viterbi al gorithm at Nyquist-rate, for linearly modulated signals corrupted by I SI and AWGN. When signalling is M-ary and ISI extends over L - 1 symbo ls, this scheme results in M + CL (complex multiplications, C is the n umber of samples per symbol), whereas the whitened-matched-filter base d Viterbi algorithm requires M-L complex multiplications.
